I just noticed that all my music that haven't been bought through iTunes store have been wiped out from the library AND from the HD. Also, when I was trying to figure out what was going on, most of the remaining music that I bought from iTunes store disapeared in front of my eyes between 2 reboot of iTunes software. Not sure when it happened if it was since v 11 or v 11.xx but I lost almost all the music Did not lose movies though, only music. Anybody ever experienced that? I am running the latest ML version.
